if the electric field is zero in a particular region of space, what does that tell you about the electric potential in that region? is the potential zero, constant, or something else? explain.

    Hello!

    If michael jordan has a vertical leap of 1.29 m, then what is his takeoff speed and his hang time (total time to move upwards to the peak and then return to the ground)

    We have the following data:

    Vf (final velocity) = 0 m/s

    Vi (initial velocity) = ? (in m/s)(takeoff speed)

    a (gravity acceleration) ≈ - 9.8 m/s² (ascension)

    d (displacement) = 1.29 m

    Since we do not need to know the time elapsed during the movement, we apply the data of the question to the Equation of Torricelli, let us see:

    V_f^2 = V_i^2 + 2*a*d

    0^2 = V_i^2 + 2*(-9.8)*1.29

    0 = V_i^2 - 25.284

    25.284 = V_i^2

    V_i^2 = 25.284

    V_i^2 = \sqrt{25.284}

    V_i = 5.028319799...

    \boxed{\boxed{V_i \approx 5.03\:m/s}}\Longleftarrow(takeoff\:speed)\:\:\:\:\:\:\bf\red{\checkmark}

    * his hang time (total time to move upwards to the peak and then return to the ground) ?

    Vf (final velocity) = 0 m/s

    Vi (initial velocity) = 5.03 m/s  

    a (gravity acceleration) ≈ - 9.8 m/s² (ascension)

    t (total time) = ? (in seconds)(hang time)

    We apply the data to the first Equation of uniformly varied motion, see:

    V_f = V_i + a*t

    0 = 5.03 + (-9.8)*t

    9.8\:t = 5.03

    t = \dfrac{5.03}{9.8}

    t = 0.5132653...

    \boxed{t \approx 0.513\:s}

    Now, total time to move upwards to the peak and then return to the ground, lets see:

    t_{total\:time} = ascension\:time + return\:time

    t_{total\:time} = 0.513\:s + 0.513\:s

    \boxed{\boxed{t_{total\:time} = 1.026\:s}}\Longleftarrow(hang\:time)\:\:\:\:\:\:\bf\blue{\checkmark}

    answers:

    takeoff speed = 5.03 m/s

    hang time = 1.026 s
